Another option for those batteries would be to just buy some Flux battery cases and mount them to the side of the chassis (someone on here did that on theirs). Very easy to mount those, and you can probably adjust the height that they sit at.

Didn't know about those, I'll look into that. Thanks.

I searched but couldn't find the dimensions of the Flux battery boxes. From the pics and the discussions on the web on what lipos fit in them, they don't seem much bigger than the E-Revo battery compartments which are too small.

I'll get you dimensions from mine tomorrow. I run a pair of 3S 4300's in it, and there is length to spare on them.

Here is a center shot of my ELST2.

http://i143.photobucket.com/albums/r.../E-LST2_19.jpg

I'm waiting for my buddy to get some XXL stuff cut, then will move everything over to the XXL chassis. I think we're making custom chassis too. It's a bit cramped here on the LST2 though, and I knew I'd be taking it all apart again anyway. So I didn't spend a lot of time with detail, but will.

I'm using a Revo receiver box that is screwed (tapped) into the existing tray, and a custom cut ESC tray shaped like the original one. The battery hold down is ok, and works. But it's too big, and has too much weight to it. That's going to be redesigned. I love the hold down that Maneba made!! Very nice!!

When I move over the XXL chassis, I'm going to gussy it up a bit and make everything much cleaner.

That being said... this ELST-2 with rear sways only is a pure DREAM to drive. My nitro XXL was too, so I know it's gonna rule after the conversion!!

You know what... it just dawned on me that my rear arms, shocks, sway is BACKWARDS! And you know what... it drives and rides like a dream. I wonder if there is something to that?? Oops!! I am fairly new to Losi, and didn't catch that little mistake! That's funny though!

You know... I had an idea for the ELST/XXL... but I have no ability to draw it out. I envisioned like side splash guards that bolt to the bottom of the chassis, using longer screws, but existing screw holes, and looking at the bottom of the chassis, it would appear that the guards came out about a half inch, then flair up about two or so inches. There should be enough clearance so it doesn't hit the spur gear. But what this may do, is prevent debris from splashing up onto the top of the chassis. LST bodies are so wide to account for the gear cover and pipe, that a lexan type splash guard on either side would really do the trick I think. It may also act as a side guard for crashes.

However... this idea doesn't involve side battery trays. it's for those who mount their batteries across the chassis (which I feel makes the truck unbalanced personally). If using side battery trays, you could still make side guards to fit in conjunction with the battery trays.

Does this make sense? As I said, I wish I could draw it. I could make a mock up out of cardboard though and take a picture...

j

Yep it makes perfect sense and I think it's a great idea.

I have some money coming my way and I am watching for used but clean LST XXLs on the web. I thought of Laser eye surgery again instead but at 95% success rate, I still don't trust it enough. :intello:

I just had my eyes sliced and diced and laser perfected on 1/13/10 over here in the metro Detroit area. Get it done before you're too old. I highly recommend it!

Just get an LST2 roller, then buy a XXL chassis off ebay. I got mine for 12 bucks shipped.

Yeah, get an LST2 roller and an XXL chassis on Ebay (Jenny's RC) and swap the stuff over. However, you will need to score some XXL diffs too. I don't think the LST2 has the good diff's in them.

I think the Diffs are the same, I blew 2 XXL diffs so far, and I'm running LPR's not the XXL tires....

Yep - diff's are the same. Only other thing you'l need are the XXL center shafts, also readily available on ebay - however, most chop shops seem to be selling those with the diff's.

It seems that more and more people on ebay are using Auction Snipers, It is getting difficult to win an auction. I just missed out on a sweet XXL with a lot of extras. That auction sniper outbid me automatically. But these auction snipers have one drawback I would say, when the sniper user is faced with a guy like me, the sniper user ends up paying more for a used XXL than a new one.:lol:

$680 he or she will have to pay :rofl: Plus $50 shipping. I hope it's not someone from RCM. But it did have a lot of extra parts and tools so maybe it is justified. :mdr:

I am a sniper, and I usually never over pay. I use it out of convenience so I don't have to be at my computer to bid. I'm too busy.

I always thought that the blue XXL diff cases had HD cups in them, and the LST2 diff's use plastic cups?

Also, I'm now not so sure that my rear arms aren't backwards, but that the pinkish XXL shown in this thread (can't remember the user name), is wrong. Haven't looked at the stock pix. But both of. My Losi's are this way.

XXL uses inner cup #B3537 and B3532 outer, the LST2 uses the same numbers. Now there is an optional HD inner case and gear set that you can get which has steel plates for the cross pins - but the cup is still plastic. I did this upgrade on mine.

Yes those HD diff cups are very strong. I have a few of them left since they are what I used to make the E-Revo center diffs with. Now I have been shopping around for either a XXL or a LST2 and I see a lot of different prices for them. I have no idea of a reasonnable price for a used LST.

Can someone tell me what to look for let's say:

A used XXL complete - how much?
A used XXL roller - how much?
A used LST2 complete - How much?
A used LST2 roller - How much?

I have no idea how much these things are worth used. I could do with a LST2 since I already have the HD diffs, a XXL chassis, a XXL body and XXL middle shafts.

Thanks

Well I finally bought an LST2. It's a roller that was never used, brand new.

I already have:

- XXL chassis
- XXL body
- XXL diffs complete with blue cases and long shafts

When I paid for the LST2 on ebay, I went shopping for other stuff that might come in handy. Stuff like:

- RCM Drive Cups - Hardened Steel. I got 4 of those, 2 for spares
- Some Turnigy thick heat shrink tubing for batteries. I want to try those.
- Complete set of parts needed for the Muggy steering set up
- A 3 mm by 9'' X 11.85'' sheet of CF
- A 2.5 mm by 9'' X 14'' sheet of CF
- A JR DS8711 Ultra Torque SX Digital Servo
- A Neu 1521 1Y 5mm shaft motor (I wish I could have bought this from Mike also but he was out of stock and I was in a ''shopping gotta get it NOW'' kinda mood.
- Losi 17 mm wheel hex conversion
- Losi LST2 sway bar kit
- I also went ahead and ordered new tips for my hex wrenches.

The wife is going to flip :yes:

So where's the new LST forum? Did I miss the official opening? :smile:

I don't know when I will be able to start the build, my garage is a mess and I have to build a backyard shed to move a lot of stuff out of the garage so that I can start organizing it as a workshop. Which means electrical work, plumbing, insulating, dry walling, heating, etc. A lot of work.

Enjoy that 1521/1Y! Its a monster for sure!! Especially on 6s!

You sound like me... Putting off rc for the big projects!!!

Best thing I can do with my time right now is decide what rc stuff i want to keep and move the rest on. Trying to get down to a single 9ft tall shelf unit for rc. Right now I have 2 of those shelf setups, and a bunch of stuff littering the ground. I am sure I could carefully organize what I have and get it all on the shelves, but I really need to part ways with the stuff I never plan to use. Maybe get down to 20 rcs, including the boats!

Good luck with the xxl project, I will be interested to follow your progress. When the dead of summer hits here I will get back to rc, too hot to be outside then!

Stuff is slowly starting to come in. I got the Neu 1521 1Y and the LST2 for now. In 2006, I bought a Revo 3.3 even though my LHS owner at the time was advising me to get the Losi LST. Now that have the Losi in front of me and had a chance to look it over I'm thinking, why didn't I listen to that guy. My last experience with Losi kits (aside from my son's present Mini-T) was with a JRXT stadium truck, a XX buggy and the Street Weapon. I loved Losi kits in the past and I'm glad I have a new one to play with now.

This is a slow build. Sifting through boxes to find my tools and then move boxes to set up an area to fabricate a part is time consuming. Nevertheless, I am slowly moving forward with this build. I am now figuring out a way to fit the Muggy steering bellcrank with minimal modification to the chassis rails.
I am trying to win an auction on an E-Revo tranny on ebay but I haven't been lucky yet. I plan on upgrading the slipper to the Hot Racing double slipper but I won't use stock pads. Instead I will make an aluminum disk like I did in the past with the E-Revo.
Running the E-Revo tranny means I will have to fabricate another motor plate. The one I have now has been very good at supporting the CC 2200 Kv but I fear that the heavier 1521 might need some more support so I'll be looking at making something to support the rear of the motor, something like this but probably less pretty.

Good luck with the ebay on those. I tried for months on them, and they sold for 40 to 50 every time, then were magically relisted the next day. I reported the crap out of them, but apparently the ebay rules have no teeth. I've got a new maxx tranny that I bought a couple months ago that I'd sell you for what I paid for it (I'd have to go back and look it up).

Thanks for wishing me luck JT, I just won an E-Revo tranny for $35 plus $6 for shipping :yipi:

I think I have the Muggy steering almost figured out, I'll post pics tomorrow. In the mail today were the Losi sway bars, the Losi 17 mm hex adapters and RC Monster drive cups.

I do what I can for ya!!!!

Wow, I can't believe that I didn't realize this. Maybe there is a difference between the RAM/LST diff's and the LST2/AFT/XXL diffs then? Cuz I was sure there was one.

I've heard great things about the Nova cups. I'm not going to bother with any of that until something breaks.

Have you ever checked this forum out?
http://hdrcvideos.com/forums/index.p...83e0f6e7483015

It's AWESOME. It's the RCM of LST trucks. Friendly people too.

jpoprock,

I'm going to have to check this forum out. Thanks for the link.

A few pics of what I've been doing. I made temporary plates out of Plexi, the top plate and the front skid plate. Being transparent, it makes it easier to see where to put everything and how well it works. Three things had to be trimmed a bit from the XXL components. The plastic ring that snaps on the chassis and in which the output of the diff slips into. It had to be trimmed on either side because the ball ends of the turnbuckles hit it preventing full steering throw. The front corners of the top plate have small notches done also to keep the turnbuckles' ball ends to hit it on the suspension's full compression. Last was the chassis rails, they had to be trimmed very slightly to allow the bellcranks to move freely.

The Muggy steering assembly had to be trimmed a bit also. The posts are now 40.5 mm high. Both the bellcranks had to be trimmed to fit the shorter posts. This means shorten them and bore the hole that houses the bushing a little deeper.

I fabricated one extra part which is the extra front skid plate that holds the bottom of the steering assembly. By going with two skid plates I was able to fit the steering without trimming off too much of it. So the stock skid plate will act as a shim basically and the extra one will hold the steering.

The steering posts are placed on the chassis 48.3 mm apart. I used a turnbuckle to join them together because I wanted to have something adjustable there. I didn't know what the length of this turnbuckle should be to achieve a good ackerman so it made it easy to play around with the length to get to the ackerman I think is acceptable. The turnbuckle ended up being 47.5 mm long from the center of the screws.

There's one thing that bugs me about this set up and that's the middle shaft going to the tranny. I don't know if the part of the bellcrank that attaches to the servo's turnbuckle will hit the shaft. It depends on how far the shaft will dip down to meet the tranny. If it dips down enough, it should be fine but if it ends up being parallel to the chassis top plate then I'll have to trim the bellcrank.

All in all, it looks like it's going to work very well but it was a lot of work to make fit. Just a little cutting and grinding but on many parts. Enough talking, here's the pics. Input is welcomed as usual.

Nice Job so far!!!!! A for effort!! Is the muggy steering better than the original? Is there a better turning radius? I would think yes or why else would you do it? let me know. I have a converted aftershock.

Intersting info there MC. I can see right now that I might have an issue on mine if I use the Muggy steering. My center shaft is going to be angled towards the servo, and slightly up from center.

When you did the mod to shorten the post, are you certain you did it from the correct side? I seem to recall from reading about someone else who did this that they did not have to bore out the bushing hole....but I am not certain about that. I almost wonder if they didn't instead grind out the chassis rail.

Hey guys... I broke a couple pins inside my tranny and have repaired numerous diff's with broken pins. I've heard that the HPI 2.5 Hellfire pins work well. But do you think that a 3mm rod would work too? Cuz if so, I found this: http://www.diversehobbies.com/catalo...roducts_id=108 3x275mm Titanium rods. If 3mm will fit, you can cut your own to length, and surely they would hold up better than the steel pins that keep breaking? Just a thought.

jason

Couldn't sheared pins be a sign of a diff that might not be shimmed properly? You've probably got too much free rotation of the input before it engages the gears. I don't think I have ever sheared a pin - but I'm also not going to claim that I know what I'm doing when shimming!

Yeah, it could that for sure. The diff's I've broken pins on where non-HD diff's, AND they were inherited. So, they were not shimmed. Any diff that I rebuild now will be shimmed. I'm in need of about 4 HD cups though! DOH!

My tranny pins snapped... but I'm not sure why. Could have had my slipper too tight. The truck in question is a BL E-LST2 on 6s with a Neu 1515 2.5d. It's a monster. I had my slipper all the way tightened, but not FIRM. Hard to say what happened.

I'm experiencing a "click" in the rear diff (which is an HD diff), so I'm betting that I have a pinion that's going. Could be because of the slipper, AND because I do a lot of loose gravel drifting. I always try not to land jumps on power. I'm sorta surprised that I'm getting a click in the diff though.

Does RCM sell a ring/pinion that is heavy duty that will fit in the Losi diffs? Or do I have to buy a Losi kit?

Maybe you could flip the whole assembly the other way and have the lever on the other side, you would have the adjusting collar for the tension near the top plate instead of the bottom but IMHO, this collar is adjusted once for the desired tension and then you never touch it again. It is not an adjustment that you mess around with constantly. If your shafts are slightly off center that means you would have enough clearance since I found out that only a half mm more is needed for the lever not to touch the shaft.

So what makes you think their way was the right way :tongue: :intello: Seriously, there's more than one way of doing it, I did it my way and it works pretty darn good.

I did a lot of stuff today. So my fear of the bellcrank touching the shaft materialized today. I ended up shaving a tiny bit off the lever for clearance so that it would work in this plexi mock up. I will solve this little problem definitely when I make the CF top plate and the aluminum part that goes over the front skid plate by spacing the two bellcranks 2 mm more apart. 1 mm on each side which will take that lever away from the shaft just enough so that it doesn't touch.

http://i177.photobucket.com/albums/w...XL/th_xxl1.jpg http://i177.photobucket.com/albums/w...XL/th_xxl2.jpg

I tried with the inverted servo set up and it just bugged me. Don't know why but it did so I flipped the servo right side up and I just like it better that way.

You will notice that this top plate looks kind of grungy and the openings are too large and the cuts look awful. This is only a mock up. The finished product should look a lot cleaner.

This middle skid is not exactly what I intend to do. I just duplicated the stock middle skid and added wings to it for the batteries. The final CF skid will be more refined and look more elegant than this.

http://i177.photobucket.com/albums/w...XL/th_xxl4.jpg

But it does place the batteries nice and low. But not too low.

http://i177.photobucket.com/albums/w...XL/th_xxl3.jpg

I had a couple of those alu plates that go under the shock towers so I took one. cut it, grinded it, sanded it, drilled and tapped it and made this.

http://i177.photobucket.com/albums/w...XL/th_xxl5.jpg

It goes there in front of the rear shock tower to hold the Traxxas receiver box.

http://i177.photobucket.com/albums/w...XL/th_xxl6.jpg http://i177.photobucket.com/albums/w...XL/th_xxl7.jpg

This will be the final layout. My original plan was to put the MMM in the front but with the size of the 1521 1Y, it looked a little cramped so I decided to place it just behind the tranny. I just think that it makes the layout look cleaner and it gives lots of room to work on anything.

http://i177.photobucket.com/albums/w...XL/th_xxl8.jpg

I wanted the tranny to be in the absolute center but the XXL middle shafts were just a little too long so I had to off set the tranny 4 or 5 mm to the rear and use a LST2 middle shaft in the rear. With the XXL middle shaft in the front, it all went together very well. The drive train rolls very freely with no binding.

On a side note, I took the whole thing with the batteries on it in my hands and let it drop from 2 feet high and was amazed at the amount of damping these big shocks give the truck. This thing is a jumper for sure.

I seriously don't know. This is my first experience with the LST. I'm modifying and converting the thing but I never drove it. :lol: I hope to soon.

That mock up looks very very nice:intello: If I could make one criticism though, it would be the esc is a long way from the motor wires.

Awesome build sir crasher :yipi:

Thanks and yes, this is one thing that tore me inside when I decided to put the ESC where it is.:smile: It was really too tight in the front. I will have to solder on longer wires no matter where I place the ESC. They will just be a little longer. Like 4 inches longer :lol:

As always, your build is turning out awesome. Can't wait to hear how it does in action.

Can't wait to find out how well it will run also. Up to now this has been a pretty easy build. The hardest part was figuring out the Muggy steering but the rest was pretty simple. I seriously thought it would be more difficult and complicated. I am still waiting for the CF plates to come in and I just ordered a 2.5 mm thick T6 6061 alu plate to make the front skid part to hold the steering bellcranks and a proper servo horn from Racers Edge.

Looking great MC. Wish mine was coming along as fast as yours is.

Your layout is nice with a very centered Cg. I'm hedging my bet that I'll need more weight on the front to alleviate wheelies - unfortunately, we are both going to end up locking ourselves into whichever config we build!
